How do I check if a string contains a list of characters?

Question

How do I check if a list of characters are in a String, for example \"ABCDEFGH\" how do I check if any one of those is in a string.

Answer 1

This is how it can be achieved using Pattern and Matcher,

Pattern p = Pattern.compile("[^A-Za-z0-9 ]");
Matcher m = p.matcher(trString);
boolean hasSpecialChars = m.find();

Answer 2

This seems like a Homework question... -_-

You can use the String.contains() function.
For example:

"string".contains("a");
String str = "wasd";
str.contains("a");

but you will need to call it once per every character you want to check for.
